The share of this ZIP’s land area inside FEMA’s 1%-annual-chance floodplain — the “100-year” flood zone, where flooding has about a 1-in-100 chance in any given year.

Full methodology ›The read
By its overall health score, Castleton, Illinois (ZIP 61426) lands in the top 50% healthiest ZIPs nationally (15,911th) and the bottom 46% of Illinois (745th).
The measures split the difference for this area: modeled pfas is in the bottom 1.7% nationally, and housing-cost burden stands at the national minimum. Modeled transportation noise settles at the national minimum, and homeownership lies at the national maximum. Floodplain exposure resides at the national minimum, and modeled expected annual loss lands in the bottom 7.2% nationally. Against that, modeled arsenic registers in the top 0.6% nationally, modeled colon screening sits in the bottom 3.1% nationally, and poverty rests in the top 4.0% nationally. Modeled binge drinking is in the top 6.2% nationally.
Weighed against the ZIPs nearby, home broadband subscription runs far lower than the surrounding ZIPs on this measure. To translate a couple of terms, arsenic is a natural groundwater contaminant, here a modeled estimate of the chance private-well levels exceed a benchmark. Pfas is the man-made "forever chemicals" that build up in the body and environment instead of breaking down; here a modeled estimate of the chance a private well contains them. Expected annual loss is FEMA's modeled estimate, in dollars, of average yearly harm to people from natural hazards. Overall, the nearest healthier neighbor is ZIP 61491, just across the boundary.

How these were chosen: only ZIPs with a published Score appear — a nearby ZIP with too little data to score won’t. Nearby means closest by distance between ZIP boundaries, which can cross state lines. A similar health profile is a close match across the nine Score domains, not similar demographics. Distances are measured between ZIP boundaries — ZIPs that touch share a border. How distance is measured

About the ± — it’s this estimate’s give-or-take (statisticians call it the standard error). The true life expectancy for this ZIP most likely falls within 2.42 years of 82.5, and it’s very unlikely to be off by more than twice that.

How these lists were built: they draw only from ZIPs that have a published Score, so ZIPs with too little data to score are not listed. Distance-based lists use distance between ZIP boundaries with no state filter, so an out-of-state ZIP can appear. Statistically similar means a close match across the nine Score domains, not a demographic match: the measure is the cosine similarity between two ZIPs’ domain scores, taken over the domains both ZIPs have data for and only where that overlap covers at least six of the nine — and where no ZIP clears that minimum-overlap floor, that list is left out rather than filled with a weak match. How distance is measured
